Elon Musk, The Boring Company CEO, has quoted $1 billion to build a commuter tunnel under Australia’s famed Blue Mountains, which divide Sydney from the country’s vast western interior.
He was responding via Twitter to a query by New South Wales (NSW) member of parliament Jeremy Buckingham, who described Sydney as choking with traffic and asked the cost of a 50-km underground tunnel.
“About $15 million per kilometer for a two-way high-speed transit”, Musk responded. “So probably around $750 million plus maybe $50 million per station.”
Musk did not specify if he was referring to US dollars. The Boring Company is currently testing similar tunnel systems to ease congestion in Los Angeles, with a prototype stretch being completed last month.
